feat(admin): add Croatian translation

[luxapan]

What

Adds Croatian (hr) translation for the Medusa Admin dashboard.

Why

Allows Croatian-speaking merchants and admins to use Medusa Admin in their native language.

How

• added packages/admin/dashboard/src/i18n/translations/hr.json
• registered hr in packages/admin/dashboard/src/i18n/translations/index.ts
• added Croatian language entry in packages/admin/dashboard/src/i18n/languages.ts

Testing

• reviewed the translation for terminology consistency
• validated JSON structure locally

---

Note

Low Risk
Low risk localization-only change that adds a new translation bundle and registers it; primary risk is missing/incorrect keys causing fallback strings or build issues if the JSON/locale import is misconfigured.

Overview
Adds Croatian (hr) support to the Admin dashboard by introducing a full hr.json translation bundle and registering it in the i18n translation map.

Updates the language selector configuration to include Hrvatski and wires in the date-fns Croatian locale for date formatting.

Thanks! This PR only adds the Croatian admin translation and registers the locale, so it shouldn't require a version bump. Please authorize the Vercel preview if needed.

Thank you for your contribution! 🎉

After an initial review, this PR looks good to us. Here's a summary:

✅ PR template is complete
✅ Follows admin translation contribution guidelines
✅ New language file correctly named with ISO-2 code (hr.json)
✅ File registered in translations/index.ts and languages.ts per the contribution docs
✅ No unrelated code changes

Notes:

• The team will spot-check during final review that the values in hr.json are actual Croatian translations rather than English copies — this is a standard verification step we do for all translation PRs.

A team member will do a final review before this is merged. We appreciate your patience!
